Troubleshooting the System
Telephone Does Not Ring
Possible Cause 6:
• If the replacement telephone does not ring, there may
be a problem with the system wiring or the control unit.
To test one wiring possibility, go to Possible Cause 6.
NOTE:
The following procedure may help Lucent Technologies
Helpline technicians analyze your problem. You should not
perform this procedure, however, unless you have
experience removing the control unit cover and working with
the control unit extension jacks. Before proceeding, consult
system planning Form 2a, System Numbering: Extension
Jacks.
!
CAUTION:
If you must check something on the control unit, proceed
with caution. Do not stand on a box or chair to reach the unit
if it is installed out of easy reach. If you do not have a stable
ladder or other proper equipment, do not proceed; wait for
the Lucent Technologies technician.
The wiring is faulty somewhere in the system.
What to do: Test the control unit module and jack into which
the telephone is plugged.
• Identify the port where the nonfunctional telephone is
connected. Identify a second port in the same module
connected to a functional telephone and unplug the
jack from the module. Plug the jack for the non-working
telephone into the extension jack that is now open. If
the telephone works, call the Lucent Technologies
Helpline at 1-800-628-2888 (consultation charges may
apply).
• If the telephone still does not work, call the Lucent
Technologies Helpline at 1-800-628-2888 (consultation
charges may apply).
